The median land area among these 100 entries is 553.911 mi². The first and last entries span 21.594 square miles. This median describes the entries on this page, not the full national dataset. Pagination is a browsing boundary, not a distinct geographic region.

A difference of one position means only that two entries are adjacent in this ordering. Their actual size difference can be tiny or substantial. Compare the measurements as well as the rank, and use the original square-meter fields when rounded labels appear equal.
